Embodiment Construction

[0072] Figure 4 is a front view of a storage device according to an embodiment of the present invention. Figure 4 The memory device shown includes a circuit board 400 . The circuit motherboard 400 is a circuit board in the form of a PCIE half-height card, which can be connected to a computer through a PCIE slot. Circuit daughter boards 410 , 420 and 430 are arranged on the circuit motherboard 400 . In one embodiment, flash memory chips 411-413, 421-423, and 431-433 are respectively arranged on the sub-boards 410, 420, and 430, so that the sub-boards 410, 420, and 430 Figure 4 The storage devices shown provide storage capacity. A flash memory controller (not shown) is also disposed on the circuit motherboard 400 to control access to the flash memory chips on the circuit daughter boards 410 , 420 and 430 and process interface commands from the computer. Although in Figure 4 shows a storage device with a PCIE interface including a flash memory chip, but those skilled in ...

Abstract

The invention relates to a memory device, which comprises a first circuit board, a second circuit board and a third circuit board. A plurality of memory chips are arranged on the first circuit board, a plurality of memory chips are arranged on the second circuit board and a controller and a host interface are arranged on the third circuit board; the first circuit board is coupled with the third circuit board and the second circuit board is coupled with the third circuit board, so that the memory chips arranged on the first circuit board and the memory chips arranged on the second circuit board can be accessed through the controller by virtue of the host interface; the memory chips on the first circuit board are configured to in a first channel and a second channel, the first channel comprises a first quantity of memory chips, the second channel comprises a second quantity of memory chips and the first quantity differs from the second quantity.

Description

technical field [0001] The present invention relates to electronic equipment, and more particularly, the present invention relates to a printed circuit board system for a solid storage device (Solid Storage Device, SSD). Background technique [0002] Similar to mechanical hard drives, solid-state storage devices (SSDs) are high-capacity, non-volatile storage devices used in computer systems. Solid-state storage devices generally use flash memory (Flash) as a storage medium. High-performance solid-state storage devices are used in high-performance computers. [0003] In the patent application WO2011085131A2, it is provided as Figure 1A , 1B Scalable-capacity SSD shown. Figure 1A In the solid state disk, a plurality of connectors 204 and a flash memory chip (not shown) are arranged on the main printed circuit board 205 of the solid state disk. Connector 204 is removably connectable to a daughter card. Daughter cards may include flash memory chips to provide additional st...
